Application filed August 13, 1,917. Serial No. 185,841.

To all whom it may concern:

Be it known that I, GIUsErPn TEs'rA,residing at No. 209 East 116th St, in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Firearms, of which the following is a full, clear, and exact specification.

This invention is particularly directed toimprovements in firearms of the class described in Letters Patent granted to me July 4, 1899 and bearing Number 628,130.

The primary object of this invention is the devising of a firearm of the type referred to, in which all of the cartridges may be fired at the same time, or if desired, only 'a part may be fired at one time and another part at a subsequent time. a

R ferring to the drawings forming part of this specification- Figure 1 is a perspective view of a revolver {comprising my improvements.

Fig. 2 is a plan view of same. 7

Flg. 3 1s a detail view of the firing mechanism with certain parts removed for more clearly revealing the interior mechanism.

Figs. 4 and .5 show the cartridge holder, Fig. 5 being the cartridge supporting plate and Fig. 4 being the retaining cover for same.

Fig. 6 is an end view of the plate with the cartridges assembled.

Fig. 7 shows a cartridge partly broken away to give a clearer understanding.

Fig. 8 is a section through the broken line 8-8 of Fig. 5, and Fig. 9 is a section through the line 9--9 of Fig. 2.

In the preferred embodiment the barrel 1 is composed of a cluster of ten separate bores and is pivotally secured at 2 to the stock 3 and maintained in firing position by the locking pin 4, all of which resembles in the main the corresponding parts disclosed in my patent above referred to. In the present instance, however, the locking pin 4 is provided with a thumb actuated latch projecting from the side thereof, which 1s adapted to engage a groove 6 formed in the stock 3 for firml pressing theouter end simultaneouslywith the forcing of the latch piece 5 upward. The pin 4 is adapted to rotate in its retain mg bore in the socket so that the latch may be raised to free it from the socket, whereupon the pin 4 is automatically thrust rearward; in the usual manner for releasing the barrel to permit thejoint to be broken, as seen in Fig. 1. This enables the discharged cartridges to be removed and a fresh charge to. be inserted, the cartridge plate being simultaneously thrust outward for better facilitating the manipulation of the cartridges. Referring now to the mechanism enabling the cartridges to be fired all at the same t me or by separate groups as desired, I provide a breech plate "8 carrying the firing 9, one for each group ofthef cartridges A. In the present instance as only two groups are shown but two firing pins are needed.

Therejare two hammers 10-10, one for each firing pin and as their controlling mechanism is similar a description 01f one will suflice. The hammer 10 is pivoted to the stock the pin 11 and is somewhatin the shape of a bell'crank, the forward end serving as the hammerproper for striking the firing pin, while the rear end is pivoted to an arm 12,.which engages one end of the bent spring 13, the other end being sup ported by the fixed piny14 and extended to abut against the lug 15 on the hammer to. serve as a stop for limiting the movement of the latter when released. The pin 11 which is fixed to the hammer has the finger actuated arm 16 secured thereto whereby the hammer may be. thrown backward against the tension of spring 13 to cocked position.

i A single. trigger 17 provided for con- 7 sesam y referees. it s is force the hammeragainst the firing pin 'th'usfire" the group ofc'artridges A. It'w1llj further be'observe'd that if but one hammer f is set to cocked position the trigger will only operate this hammer, after? which the otherl' hammer may be similarly set and operated for firing the second" group. of cartridges.

on the other hand, if both hammers" are cocked at the same time .then by 'a single pulling of the trigger both will be released I and; all the eartridgeswillj be fired simultaneously;

- -A further important object of invention is the devisingof a cartridge holder whereby either'of the groups of cartridges maybe fired without exposing the cartridges of the other group to the dangerof'being unintentionallyfired. In'fithe preferred embodimenti-theflplatel is providedjwith the holesi23 through which 'thecartrid'ges-A protrude, the same being arrangedgroups I consisting in the present instance of five cartridges whichare fired at the same time.

Theholesare provided with the shoulders 24 to engage the heads 25 of the cartridges to secure them within theplate; The plate is provided with a chamber26 to s-whichis secured a percussion cap 27 Oneof these is provided for each group" of cartridges 7 trally of the group. The percussion cap is and is preferably disposed more or less cenexposed through a suitable orifice .in the cover in position to register 'with'the-firing pin 9 to be fired thereby when theftr igger is pulled; V Grooves 28- are rprovided, connect 1 ing the cap with the cartridges and the cartridges are provided with holes 29in alinement with these grooves whereby they are fired upon'the firing of 'thie cap. The cartridges are further provided with lugs 30. which engage with slots 31 formed in the holes 23 inforder to insurela positivealine mentof the holes, 29 with the grooves 28. V The plate is moreoverprovided with a hole '32 for permitting the lock bolt 4 to pass therethrough when looking the barrel; A cover 33 is providediwith a marginal fiange i I 34 whichis adapted to fit snugly about the plate 7. Holes 35 are-providfedin the cover to. register with the caps order to leave themexposed in- -line with the firing pins, as alreadyrnentioned- In order to confine;

the flashtof'powderin the rooves 28, I pro-v videtongues 36 radiating rom the holes 35 and adapted to nt infthe grooves 28' but leaving. in th-e base thereof suflicient room 'for the flash. T0 further prevent any possibil ityof the fiash-of powder from thecap of one group from-passingover to the other group I.provi de a shoulder 37 aboutthe "hole 32 and a grooveBSextending acrossthe plate'to divide it in halves;- The cover 33 is f correspondingly provided with a'fiange'39 'and beadllflz disposed respectively to be eneeigaged by the a shoulder 3.7 and groove 38 thereby providing partition 7 wall separatt e tWo groups of cartridges;
